What is my IP address from the outside? What is my DNS info? Who is my ISP? What is my Whois info? What is my browser header data?
Ever wondered what your computer looks like to the outsiders, as in what your digital fingerprint looks like?

Here is some information about you, such as browser type and IP address, and
some information about this site, such as server type and IP address. There are also Whois and DNS dumps on your ISP, if available.

Actually, "whoami" is an old unix command that tersely prints the effective user id.
The "id" command is more useful, but whoami has persisted over the years.

The unix/linux command to get your box's IP info is "ifconfig" or "ip a". The equivalent Windows command is "ipconfig".
